【紅外】有誰自己計(jì)算過ZEMAX中的YNI值
在紅外制冷系統(tǒng)設(shè)計(jì)時(shí),一個(gè)非常重要的一點(diǎn)是冷反射的控制,關(guān)于冷反射,有個(gè)很重要的參考量是YNI,在zemax里YNI的定義為: N[?N5~jG Z~GL5]S YNI#paraxial. This number is the product of the paraxial marginal ray height times the index times 8bxfj<O, the angle of incidence at the surface defined by Surf at the wavelength defined by Wave. RXNn[A4xfY <<UB ^v m 也就是近軸像高乘以折射率乘以入射角。
